Official Description

Transluminal balloon angioplasty (except dialysis circuit), open or percutaneous, including all imaging and radiological supervision and interpretation necessary to perform the angioplasty within the same vein; initial vein

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Transluminal balloon angioplasty is a specialized endovascular procedure designed to treat narrowing or obstruction in veins. This technique employs fluoroscopy, a type of medical imaging that allows real-time visualization of the veins during the procedure. The process begins with accessing the targeted vein, which can be done either percutaneously or through an open surgical approach. In the percutaneous method, a needle is inserted through the skin into a blood vessel located in the groin, arm, or neck. A guidewire is then threaded through this needle, and the needle is replaced with a vascular sheath to facilitate the introduction of other instruments. Conversely, the open access method involves making an incision directly over the vessel to gain access. Once the vein is accessed, a vascular catheter is introduced over the guidewire, and contrast dye is injected to enhance the visibility of the vein and to identify any areas of narrowing or disease. Following this, a balloon catheter is inserted and advanced to the site of the obstruction. The balloon is inflated with a dilute contrast dye, which serves to expand the narrowed section of the vein for a specified duration. After the inflation period, the balloon is deflated and removed. To confirm the success of the procedure, a vascular catheter is reinserted, and angiography is performed again to assess whether the vein has been adequately opened and to check for any residual stenosis that may require further intervention. The CPT® Code 37248 specifically reports the performance of balloon angioplasty on the initial vein, excluding procedures performed on dialysis circuits, and encompasses all necessary imaging and radiological supervision and interpretation conducted during the procedure.

1. Indications

The procedure of transluminal balloon angioplasty is indicated for patients presenting with specific conditions that lead to narrowing or obstruction of veins. These indications may include:

  • Venous Obstruction: Conditions that cause blockages in the veins, which can lead to symptoms such as swelling, pain, or skin changes.
  • Chronic Venous Insufficiency: A condition where the veins cannot pump enough blood back to the heart, often resulting in varicose veins and other complications.
  • Thrombosis: The presence of a blood clot within a vein that can obstruct blood flow and necessitate intervention.

2. Procedure

The transluminal balloon angioplasty procedure involves several critical steps to ensure successful treatment of the affected vein. These steps include:

  • Accessing the Vein: The procedure begins with the selection of an appropriate access site, typically in the groin, arm, or neck. For percutaneous access, a needle is inserted through the skin into the target vessel. A guidewire is then threaded through the needle, allowing for the needle to be removed and replaced with a vascular sheath. In cases where open access is required, an incision is made over the vessel to facilitate direct access.
  • Introducing the Vascular Catheter: Once access is achieved, a vascular catheter is inserted over the guidewire. This catheter is used to inject contrast dye into the vein, which enhances visualization during imaging studies. The contrast dye helps to identify areas of narrowing or disease within the vein.
  • Balloon Catheter Insertion: After the vascular catheter is positioned and imaging is completed, it is replaced with a balloon catheter. This catheter is advanced to the site of the obstruction or narrowing identified during the imaging process.
  • Balloon Inflation: The balloon catheter is inflated with a dilute contrast dye, which expands the narrowed section of the vein. This inflation is maintained for a prescribed duration to effectively open the vessel.
  • Deflation and Withdrawal: Following the inflation period, the balloon is deflated and carefully withdrawn from the vein. This step is crucial to ensure that the vein remains open after the procedure.
  • Post-Inflation Angiography: To evaluate the success of the angioplasty, a vascular catheter is reinserted, and angiography is repeated. This imaging assesses whether the blocked or narrowed vein has been adequately opened and checks for any residual stenosis that may require additional balloon inflation.

3. Post-Procedure

After the completion of the transluminal balloon angioplasty, patients may require specific post-procedure care to ensure optimal recovery. This may include monitoring for any complications such as bleeding or infection at the access site. Patients are typically advised to rest and may be instructed to avoid strenuous activities for a specified period. Follow-up imaging may be necessary to confirm the success of the procedure and to monitor for any potential re-narrowing of the treated vein. Additionally, healthcare providers may discuss lifestyle modifications or medications to support vein health and prevent future complications.
